Dissolving qab zib hauv dej yog ib eg a hloov lub cev . Vim li no: A tshuaj hloov tsim tawm tshiab tshuaj cov khoom. Nyob rau hauv thiaj li yuav qab zib hauv dej ua a tshuaj hloov , ib yam tshiab yuav xav tau. Yog tias koj evaporate lub dej los ntawm a qab zib - dej daws, koj nyob nraum nrog qab zib.
Tsis tas li ntawd, koj yuav ua li cas qhia tias kev ua kom qab zib nyob hauv dej yog qhov hloov ntawm lub cev?
Cov lus teb kws tshaj lij Dissolving ntawm qab zib hauv dej suav tias yog ib hloov lub cev . Txawm hais tias qhov zoo li tau hloov pauv (los ntawm cov muaju dawb mus rau qhov tsis pom hauv dej ) thiab cov theem tau hloov, los ntawm cov khoom rau kev daws, nws yog a hloov lub cev , tsis a tshuaj hloov , vim hais tias kev sib cog lus ntawm atoms tsis tau hloov.
Ib sab saum toj no, ua li cas rau qab zib thaum nws yaj hauv dej? Qab zib dissolves hauv dej vim hais tias lub zog yog muab tawm thaum lub me ntsis polar sucrose molecules tsim intermolecular bonds nrog polar dej molecules. Thaum ib tug ntawm cov khib nyiab dissolves nyob rau hauv dej , cov ions uas tsim cov khoom raug tso tawm rau hauv kev daws teeb meem, qhov uas lawv tau txuam nrog cov polar solvent molecules.
Ib yam li ntawd, puas yog kev hloov pauv lub cev lossis tshuaj lom neeg?
Vim li cas Dissolving Salt Ib Kev hloov tshuaj Yog li ntawd, yaj ntsev hauv dej yog a tshuaj hloov . Yog li, txhua yam ionic compound uas yog soluble hauv dej yuav muaj kev paub txog tshuaj hloov . Piv txwv li, yaj covalent compound zoo li qab zib tsis ua rau a tshuaj tshuaj tiv thaiv.
Cov khoom dab tsi ntawm cov piam thaj tsis hloov thaum nws yaj?
Qab Zib (sucrose) yog tsis yog chemically hloov los yog decomposed thaum yog yaj nyob rau hauv dej li sucrose molecules thiab dej molecules nyob twj ywm. Yog tias cov dej tso cai rau evaporate los ntawm cov tshuaj no, sucrose crystals yog tsim dua.

Puas yog huab cua hloov pauv lub cev lossis tshuaj lom neeg?
Kev hloov ntawm lub xeev yog kev hloov ntawm lub cev hauv qhov teeb meem. Lawv yog cov kev hloov pauv uas tsis hloov qhov teeb meem tshuaj pleev lossis tshuaj lom neeg. Piv txwv li, thaum huab cua hloov mus rau dej vapor, nws tseem yog dej thiab tuaj yeem hloov rov qab mus rau cov kua dej dua
Puas yog tshuaj lom neeg ntom ntom lossis lub cev hloov pauv?
Kev piav qhia: Cov khoom siv tshuaj lom neeg tsuas yog tsim los ntawm kev ua cov tshuaj tiv thaiv (kub ntawm combustion, flash point, enthalpies ntawm kev tsim, thiab lwm yam). Qhov ntom tuaj yeem tsim tau yooj yim los ntawm kev txiav txim siab qhov ntim ntawm cov khoom, tsis muaj kev cuam tshuam, yog li nws aphysical khoom
Puas yog hluav taws kub nyhiab yog qhov hloov pauv ntawm lub cev lossis tshuaj lom neeg?
Thaum cov roj hlawv nws feem ntau ua ke nrog oxygen kom muab cov pa roj carbon dioxide, dej thiab lwm yam nrog rau kev tso tawm ntawm lub zog. Los ntawm kev txhais, nws yog kev hloov tshuaj
Puas yog cov dej npau npau yog tshuaj lom neeg lossis lub cev hloov?
Boiling waterBoiling water yog ib qho piv txwv ntawm kev hloov ntawm lub cev thiab tsis yog kev hloov tshuaj lom neeg vim tias cov dej vapor tseem muaj cov qauv molecular zoo li cov kua dej (H2O). Yog hais tias cov npuas tau tshwm sim los ntawm decomposition ntawm ib tug molecule rau hauv cov pa roj (xws li H2O → H2 thiab O2), ces boiling yuav ib tug tshuaj hloov
Yuav ua li cas thaum muaj tshuaj lom neeg lossis lub cev hloov pauv?
Kev hloov tshuaj lom neeg tshwm sim los ntawm cov tshuaj tiv thaiv tshuaj, thaum lub cev hloov pauv yog thaum cov teeb meem hloov pauv tab sis tsis yog tshuaj lom neeg. Piv txwv ntawm kev hloov tshuaj lom neeg yog hlawv, ua noj, xeb, thiab rotting. Piv txwv ntawm kev hloov lub cev yog boiling, melting, khov, thiab shredding
